The Measure of Insulation Efficiency

What is R-Value?

The R-value is a critical metric in insulation, representing a material’s resistance to heat flow— the higher the R-value, the better the insulation’s performance. This measure takes into account factors such as thickness, density, and conductivity of the insulating material. When selecting insulation, it’s key to consider the recommended R-values, which can vary depending on local climate, building design, and energy efficiency requirements. However, it’s important to note that R-value solely measures resistance to heat flow, not accounting for other factors like air leakage or moisture control. Hence, professional advice is essential to accurately determine your insulation needs.
